Tips and advice straight from the Lightroom team.

Below is a preview of lens correction technology that will be included in Lightroom 3 and the Camera Raw 6 plug-in that’s part of Photoshop CS5. This is an exciting development for our non-destructive editing technology and is designed to address lens correction via two methods: Lens Profiles and Manual Correction. The easiest application of lens correction is to apply the lens profile technology that encompasses geometric distortion(barrel and pincushion distortion), chromatic aberration and lens vignetting characteristics. A handful of lens profiles will be provided by default and a Lens Profile Creator Utility will be posted on Adobe Labs allowing photographers to create their own lens profiles using a simple procedure discussed in the video below. There are also manual distortion corrections that extend beyond traditional geometric distortion and provide horizontal and vertical transform adjustments.(As well as rotation, scale and crop to visible image data tools.) Please take a look at the preview video and provide your feedback!

Lightroom 2.7 and Camera Raw 5.7 are now available as final releases on Adobe.com and through the update mechanisms available in Photoshop CS4 and Lightroom 2. These updates include camera support for the following models:

Kodak Z981

Leaf Aptus-II 8

Leaf Aptus-II 10R

Mamiya DM40

Olympus E-PL1

Panasonic G2

Panasonic G10

Sony A450

Release Notes:

Camera Raw 5.7 includes an updated demosaic algorithm
designed to provide compatibility with settings applied in Lightroom 3 beta 2.

Lightroom 2.7 also includes the same updated demosaic algorithm. The updated demosaic algorithm will appear as a subtle shift in noise characteristics at default values.

By default Camera Raw will display the image adjustments
exactly as performed in the Lightroom 3 beta 2 develop module. However, at this time Camera Raw 5.7 is
unable to support further adjustments to the following settings or tools:
